The Benchmark Abrasives 1/2" x 18" aluminum oxide sanding belt is a Made in USA, general-purpose abrasive belt for sanding, shaping, and surface preparation on wood and metal. Its narrow profile works well on portable file sanders and compact belt sanders where access, control, and detail work matter.
Aluminum oxide provides a practical balance of cutting performance and value for everyday sanding. With grits from aggressive 24 through fine 400, this belt covers material removal, blending, scratch refinement, and finer finishing without changing abrasive families.
*Wet use also depends on whether the machine and application are approved for wet operation.
Product Features
Aluminum oxide grain for general-purpose sanding on wood and metal
X-weight polycotton cloth backing for support during sanding
Closed-coat construction provides dense abrasive coverage
Butt-joint construction allows the belt to run in either direction
Wide 24–400 grit selection for coarse sanding through finer surface refinement
Made in USA
Materials & Applications
Best For: General-purpose wood and metal sanding where a narrow belt provides better access and control.
Common applications include:
Surface sanding and preparation
Shaping and contour work
Removing surface imperfections
Edge and detail sanding
Progressive scratch refinement
General fabrication and maintenance work
Machine Compatibility
Designed for machines using a nominal 1/2" x 18" sanding belt, including portable file sanders, mini belt sanders, and similar narrow-belt equipment.
Fits machines designed for 1/2" x 18" sanding belts, including:
Milwaukee® 2482-20 M12 FUEL Bandfile
Astro Pneumatic® 3037 File Sander
Always confirm your machine's required belt dimensions, configuration, and operating-speed requirements before use.
Tips for Better Belt Performance
Use these aluminum oxide belts for dry sanding only.
Allow the abrasive to do the cutting rather than applying excessive pressure.
Keep the belt tracking correctly and inspect it before use.
A sanding belt cleaning stick can help remove accumulated material from the abrasive surface when appropriate.
Always use the guards and PPE required for your machine and application.
Frequently Asked Questions
No. Benchmark recommends these aluminum oxide sanding belts for dry use only.
This belt is designed for machines that use 1/2" x 18" sanding belts. Examples include Milwaukee® 2482-20 and Astro Pneumatic® 3037. Other machines using this belt size may also be compatible. Check your exact model and installed setup before ordering, and follow the machine and belt speed requirements.
Use 24–40 grit for heavier material removal, 50–80 grit for general sanding and shaping, 100–180 grit for surface refinement, and 220–400 grit for finer finishing.
Yes. The belt is bi-directional, but follow your machine's required running direction.
Aluminum oxide is the general-purpose choice for everyday wood and metal sanding. For applications focused on heavier steel stock removal or more demanding grinding, consider the appropriate Benchmark Abrasives zirconia or ceramic belt for the material and machine.
